The PCA9500PW,118 from NXP Semiconductors is an 8-bit I/O expander featuring an integrated 2-kbit EEPROM. This device offers eight quasi-bidirectional data pins that can be independently configured as inputs or outputs, suitable for monitoring board status or controlling indicator devices like LEDs. It supports hot insertion, making it ideal for removable card systems.
The expander operates with a supply voltage range of 2.5V to 3.6V and communicates via the I2C-bus and SMBus protocols at clock frequencies up to 400 kHz. The integrated EEPROM can store board manufacturing data or error codes for diagnostic purposes. The PCA9500 appears as two separate devices to the bus master: one for the GPIO and one for the EEPROM, with fixed I2C-bus addresses similar to PCF8574 and PCF8582C-2 respectively.
Key features include internal power-on reset, noise filters on SCL/SDA inputs, and no glitch on power-up. All channels are configured as inputs upon power-up. The device is supplied in a 16-TSSOP package suitable for surface mounting.
Applications for the PCA9500PW,118 include board version tracking, configuration, health monitoring, and status reporting in multi-card systems for telecommunications and networking equipment. It serves as a drop-in replacement for the PCF8574 with the added benefit of integrated EEPROM.
